3. A cable connecter including two square end pieces with lugs at their corners, the lugs on each piece projecting toward the lugs on the other piece and forming a chamber between the pieces and their lugs, a cross-shaped intermediate clamp piece having arms guided to slide between the cornerlugs of the end pieces and clamp screws passing through the corners of the end pieces and their respective lugs for drawing the end pieces toward each other and clamping conductors inserted between the end pieces and the intermediate clamp piece.

4. An electrical connecter including two end pieces and a central piece providing two recessed wire receiving paths mutually bisectlng at substantially right angles between the central piece and the inner face of each end piece, one of each of said two paths on the end pieces being recessed to a depth greater than the other, the central piece having two substantially similar wire receiving grooves mutually bisecting at substantially right angles ,on each of the faces of said central piece adjacent an end piece, means for aligning said pieces so that the paths on the end pieces align and may cooperate with the grooves on the central piece and for selectively positioning said end pieces so that the deeper paths may lie in different planes and in either the same direction or at substantially right angles to each other, and means for drawing said end pieces toward each other and toward the central piece whereby wires of various sizes may be clamped in said paths in either parallel or crossed relation, the central piece being movable between the end pieces, and the means for aligning said pieces being arranged at uniform distances from the central axis of the pieces.

5.'An electrical connecter including two end pieces, a central piece between the two end pieces and having on each face thereof adjacent an end piece grooves arranged at substantially right angles and bisecting in the central portion of each face of said central piece, a multi-part clamping means for drawing the end pieces toward each other with a central piece therebetween, each part of said clamping means being located at substantially the same distance from a central axis through said pieces and spaced substantially equi-distantly from each side of a central piece groove, guide means to direct movement of said central piece with respect to either end piece whereby a conductor may be clamped between one end piece and the central piece in a diflerent plane from and either parallel or substantially at right angles to a conductor mimosa which may be clamped between the other epd piece and said central piece.

6. An electrical connecter including two end pieces and a central piece providing two wire receiving paths mutually bisecting at substantially right angles between the central piece and the inner face of each end piece, one of said paths on each end piece having a groove therein, the other path being flat-surfaced except where the groove intersects it, the central piece having two wire receiving grooves mutually bisecting at right -angles on each of the faces of said central piece adjacent an end piece, meansfor aligning the grooves on the end pieces with the grooves on the central piece and for selectively positioning said pieces so that the grooved paths in the end pieces may lie in different planes and in either the same direction or at substantially right angles to each other, and means for drawing said end pieces toward each other and toward the central piece whereby wires of various sizes may be clamped by said paths in either parallel or crossed relation, said aligning and positioning means and said drawing means including a plurality of screw bolts operatively engaging the end pieces, said central piece being free to slide longitudinally of said screw bolts and position itself between said end pieces, each end piece being reenforced in thickness on the outside and substantially across at least the grooved path therein.

7. An electrical connecter including two end pieces, a central piece between the two end pieces and having on each face thereof adjacent an end piece grooves arranged at substantially right angles and bisecting in the central portion of each face of said central piece, a multi-part clamping means for drawing the end pieces toward each other with the central piece therebetween, each part of said clamping means being located at substantially the same distance from a central axis through said pieces and spaced substantially equi-distantly from each side of a central piece groove, guide means to direct movement of said central piece with respect to either end piece whereby a conductor may be clamped between one end piece and the central piece in a different plane ,from and either parallel or substantially at right angles to a conductor which may be clamped between the other end piece and said central piece, at least one of the and pieces having projections extending toward the other end piece and constituting at least a part of said guide means for the central piece, said clamping means extending through said projections, and said central piece having re-' cessed corner portions to receive and be guided by said projections, said central piece being of cross shape.
